Title: Integrating type analogue-digital converter
IPC: H03M1/00
Filed: 1973-04-27
Abstract: 1385455 Analogue to digital converter TEKELEC AIRTRONIC 27 April 1973 [1 May 1972] 20048/73 Heading G4H In a dual romp analogue to digital converter in which the unknown voltage is integrated for a period T 1  and a reference voltage is then applied for a period T 2  to reduce the integrated voltage to a second threshold voltage, the period T 1  is divided into A subperiods and the reference voltage is also applied to the integrator input during each subperiod that the integrated voltage at the beginning thereof exceeds a first threshold voltage. Clock pulses are fed to a counter whenever the reference voltage is applied to the integrator. The reference voltage is of opposite polarity to the unknown voltage and of a magnitude such that the integrator output is never less than zero. As described, the unknown voltage E x1  is applied as a current I 1  through AND gate 14 and OR gate 16 to integrator 18. The integrator output voltage is applied to comparator 50 which produces an output at A when E c  exceeds a first threshold voltage E 1  and an output at B when E c  is less than or equal to a second threshold E 2 . A reference voltage 8 in the form of current I 2  can be applied to the integrator by OR gate 16 and either AND gate 22 or 24 and also via OR gate 26 to enable gate 28 which passes clock pulses of frequency f 1  to counter 14B whose final count N 0  represents voltage E x1 . An oscillator 38 of PRF f 0  feeds a counter 34 of capacity N 1  which determines period T 1  and a second counter 36 of capacity N A = (N 1 )/(A) which determines each subperiod. Operation.-Operation of start circuit 40 starts oscillator 38 and feeds pulses of frequency f 0  to counters 34 and 36. The output #N 1  of counter 34 is inverted at 54 and enables gate 14 feeding current I 1  to the integrator. At the end of the first subperiod a signal N A  is generated by counter 36 (which recycles) and is fed to AND gates 44 and 46. If there is a signal at comparator output A, flip-flop 48 is set and gate 22 enabled to pass reference current I 2  to the integrator and pulses of frequency f 1  to counter 32. If there is no signal at A, flip-flop 48 is reset via gate 46 and inverter 52. This is repeated at the end of each subcycle, the resetting of flip-flop 48 stopping current I 2  if it is flowing. At the end of period T 1  when a count N 1  is reached in counter 34, the output N 1  stops. Current I 1  via inverter 54 and gate 14, resets counter 34, stops oscillator 38 and sets flip-flop 42 which enables gate 24 to supply current I2 to the integrator and pulses of frequency f 1  to counter 14B. The count and current stop when a signal is generated at B on threshold circuit 50 signifying that E c  is less than or equal to the second threshold voltage. This signal resets flip-flop 42. In alternative embodiments the ratio of f 1  to f 0  may be controlled or varied during the conversion so that it is non-linear. Other arrangements of counters are also described.

Filed: 1965-05-13
Abstract: 1,074,979. Lasting machines. E. G. HENKEL, [trading as EUGEN G. HENKEL MASCHINENFABRIK]. May 13, 1965 [May 14, 1964; Feb. 24, 1965], No. 20279/65. Heading A3B. A lasting machine has a pair of forepart wipers 4 and a pair of wiper extensions 11<SP>1</SP> for lasting the ball portion and possibility the shank, the wiper extensions 11<SP>1</SP> being pivotally mounted relative to the forepart wipers 4 so that the extensions 11<SP>1</SP> move inwardly and towards the toe of the shoe during lasting. The forepart wipers 4 are mounted on wiper carriers 25 having rollers 6, 7 which run in cam tracks 6<SP>1</SP>, 7<SP>1</SP> in a cam plate 8 and links 3 connect the carriers 25 to a crossbar 2 driven by a piston rod 1. The wiper extensions 11<SP>1</SP> carry upwardly and outwardly extending springs 12 on their upper surfaces which engage the lasting margin of the shoe and are pivoted to the forepart wipers 4 at 10. The extensions 11<SP>1</SP> have outwardly extending arms 11<SP>11</SP> carrying rollers 20 which are engaged by the bifurcated ends 14<SP>1</SP>, 14<SP>11</SP> of levers 14 which are pivoted to the machine frame at 15. The levers are rotated to pivot the wiper extension 11<SP>1</SP> relative to the wipers 4 by push rods 30 which carry rollers 32 at their ends and which are movable in guides 29. The push rods 30 are moved forward by bolts 42 mounted on bars 43 connected to the cross-bar 2. In operation forward movement of the piston rod causes the wipers 4 together with the extensions 11<SP>1</SP> to move forwardly and inwardly until the bolts 42 engage the push rods 30 to pivot the wiper extensions 11<SP>1</SP> relative to the wipers 4 so that the extensions 11<SP>1</SP> move inwardly and towards the toe of the shoe. The push rods 30 and guides 29 are connected together by a rod 38 and can slide laterally of the machine so that one push rod 30 can exert more leverage on the lever 14 than the other thus causing one wiper extension 11<SP>1</SP> to move inwards a greater distance than the other to accommodate a left or right hand shoe. The push rods 30 are shifted laterally by a lever 60 controlled by a cam 53 which is rotated by a ratchet wheel 52 engaged by a pawl 47 on the bar 43 so that the machine alternates between left hand and right hand shoes in successive cycles. In a modification (Fig. 6, not shown) the cam controlled lever (60) also controls the valve that opens the grippers (not shown) so that the gripper adjacent the wiper extension with the greater pivotal movement is opened later than the other gripper.

In a continuous stationery assembly comprising a number of record webs and a number of transfer webs, the webs having feed perforations and tear-off perforations dividing the webs into form lengths, the transfer webs 2 are coated with transfer material except at areas which register with the perforated areas. As shown, the areas 7 of transfer material on the rear faces of the transfer webs 2 do not extend to the areas of the feed perforations 5 and the tear-off perforations 6, and a transverse cut 10 crosses the line 6 and extends from the leading edge of one form length into the trailing end of the next form length. When the record and transfer forms are all separated along the cross perforations, a tab will be formed on each transfer form to facilitate subsequent separation of the transfer and record forms, and these tabs are free of transfer material. Instead of the cuts 10, V-shaped cuts 12, Fig. 5 (not shown), may be placed on the longitudinal centre line of each transfer web to form centre tabs on each transfer form. The feed perforations 5 may be of larger diameter than the corresponding perforations in the record webs.
